(54)	System and method for smoke suppression

(57) A smoke suppression system for a building (1) employs at least one pressurisation device (19) operable when a fire (31) is detected to restrict the spread of smoke in an enclosed space by raising the air pressure in at least part of the enclosed space. The enclosed space is provided with exhaust ports (14) to remove smoke by raising the air pressure to create a pressure gradient to cause smoke to move towards the exhaust ports (14). The pressurisation device (19) has a primary power supply and a secondary power supply, the secondary power supply being an uninterrupted power supply for operating the system when the primary power supply is offline.
